The Goog has a long and storied history of April Fools' Day jokes and offbeat Easter Eggs. Here's a look at some favorites.

Ah, Google – the slightly terrifying info-titan with a puckish streak. The company is well-known for its Easter Eggs and other displays of a corporate sense of humor, none more famous than its April Fool's jokes. What follows is our pick of the litter. If you're not amused, make sure to send Gmail messages about it, so that Google can improve for next year (and here are some other ways to celebrate April 1).

The first April Fool's Day joke perpetrated by Google was also one of its best, in part because most people weren't on the lookout for it. Stare at the hypno-GIF, and MentalPlex reads your mind for search queries!

Only fragmentary records of the Great Rickroll of April 2008 are available, but it seems some madman at Google activated the Internet's nuclear launch codes, causing huge numbers of links to wind up pointed at the infamous Rick Astley music video.

I honestly don't know what the hell this is supposed to be, but I laughed for about five minutes after I found it. (Original site is written in Chinese, but retains most of its hilarity thanks to Google Translate).

Google released a new streetview-esque walkthrough capability for its Lenoir, N.C., data center last year. Clearly, the pictured Stormtrooper is a hoax – one has to assume that Google's security guards would have much better aim.

This really isn't even that ridiculous any more, given the sheer goofiness of the sports drink industry. Who'd really be surprised if Gatorade came up with a similar “student edition” that ostensibly made you smarter?

Another early hit, PidgeonRank was a great excuse for Google to trot out a bunch of charts and graphs purporting to measure “wingspan vs. beak speed” and other highly relevant metrics. (Get it? Because Google measures more or less everything? There's a 32.883% chance you just laughed at this, Steve.)
